MP 3000 New Features• Protection operational while in program mode• Long Acceleration time with Zero speed switch input • Enhanced RTD monitoring and diagnostics • Motor load shedding feature for external load control• User configurable inputs and outputs for greater application flexibility • Optional Quick Release draw out case• New Armed / Disarmed Function to ensure that false tripping will not

occur on installation and commissioning• Trip or alarm option on relay failure detection• Emergency Override resets thermal bucket and timers to permit motor

starting

Cutler-Hammer18

MP-3000 Communications• Requires optional IPONI or RS232 PONI• Can Daisy Chain up to 1000 devices on INCOM LAN.• Configure set points & set real time clock .• Backward compatible with IQ1000 II.• Alarm status available over INCOM.• Event logging with date and time stamp• New feature - motor starting curve data, average current vs time,

over INCOM.– Begin 100 ms after start declaration– End 5 cycles after run transition or trip– Data points per time based on locked rotor time.– Sends both recorded curve and calculated thermal trip curve for

margin comparison

MOTOR CURRENT

TRANSITIONRELAY

• Smooth transition from reduced voltage to full voltage based on motor starting current, time or a combination of time and/or current

• Prolonged autotransformer/reactor life by quicker removal • Incomplete sequence verifies proper transition

Motors with RTDs• Separate Universal RTD Module -- Reduces installed cost by mounting

module near motor• Fiber optic connector -- Eliminates need of Copper Wire Connection to

MP-3000 (or connect both for redundancy) • One catalog number for all RTDs -- Simplifies Inventory & Ordering • Adjusts Overcurrent Algorithm -- Reduces Nuisance Trips• Extra RTD input -- Increases Temperature Monitoring Capability• Stand-alone Capability -- Lowers Cost of Monitoring Temperature of

Motors, Transformers, Other Equipment• Relay will check coherency of URTD data - e.g. rate of temperature change.• Alarming and diagnostics - will use URTD diagnostic data.• Fail-safe behavior on communications loss

Cutler-Hammer22

MP3000 MMI• Four interface operating modes• Setting mode for changing settings• Monitor mode for readout of operating

conditions• History mode for motor operation history• Log mode for detail records of trip, alarm and

start operations

Cutler-Hammer25

Log Mode

• Log book- records 100 events with date and time stamping

• Event- detailed record of 20 trip & alarm events with date and time stamping

• Start- detailed record of the last 4 starts with date and time stamping

Cutler-Hammer26

Log Event• Alarms and trips

– type of trip or alarm– date and time of event is recorded– phase and ground currents at time of trip– % of I2T capability at time of trip– phase unbalance at time of trip– Highest RTD temp in each of 4 groups

• Up to 20 events stored

14

Cutler-Hammer27

Log Start Event

• Date and time of event is recorded• Highest phase and ground current during start• Highest phase unbalance during start• The average current at the time of transition• The time taken from start to current transition• The time taken from start to actual transition
